Fuel Additives That Work

Maintain Your Lawn Mower With a Gas Additive

One of the easiest ways to maintain your lawn mower for seasons to come is by using a good quality fuel treatment like STA-BIL®. It's the official gas additive of all Briggs & Stratton® engines.

Fuel begins to degrade in as little as 30 days. Treating your fuel prevents corrosion and the gumming and varnishing of your engine's fuel system.

Fuel Additive

STA-BIL 360 Protection

To protect your engine from corrosion, add 360 Protection every time you fill your gas can with fresh, clean gas.  It prevents the harmful effects associated with ethanol blended fuels which account for nearly 90 percent of all fuel sold in the U.S. Ethanol-blended gas is especially prone to deterioration, leading to rust in the fuel tank, corrosion, gum build-up, and even severe engine damage. This is reflected in poor overall engine performance, rough running and hard starts.

  • For use in-season, when using your equipment regularly
  • Prevents corrosion caused by today's ethanol-blended fuel
  • Stabilizes fuel up to 12 months

STA-BIL Storage

Whether you're storing your equipment at the end of the season or letting some time pass between uses, curbing your fuel’s degradation and protecting your engine is crucial. Be sure to add STA-BIL storage to clean, fresh fuel before adding it in your engine's fuel tank.

  • For use when storing equipment or in limited use equipment that have dormant periods
  • Prevents carburetor gumming and varnishing  eliminating the need to drain fuel prior to storage
  • Stabilizes fuel for long-term storage up to 24 months

Add STA-BIL ethanol treatment and fuel stabilizer according to package directions and then run the engine for a few minutes to circulate the solution through the carburetor.
